“…Spindle temperature gradually tended to stable as cooling water flow increases [31]. Zhang et al [32] investigated the effect of water runner diameter and flow rate on spindle cooling during the cooling process. In a certain area, larger flow channel diameter and flow rate can reduce the temperature and radial heat elongation effectively.…”

In high-speed motors, there is a huge amount of heat generation from core and winding losses, which may result in thermal failures or motor performance deterioration. In the prevention of heat accumulation, efficient cooling technology is critical for smooth and reliable motor movement. This paper summarizes the diverse application of high-speed motor and thermal requirements, such as in electrical devices, turbo-machinery, and high-precision machine tools. Three paths of case convection—cooling, internal ventilation cooling and spindle core cooling—are analyzed. Methods for configuring thermal resistance and improving cooling efficiency are summarized. Among them, coolant flow characteristics and flow channel shapes, gas supply ventilation systems, and methods to reduce air resistance, as well as axial cooling and integrated heat pipe structures, are extensively investigated. Finally, the development prospects of high-speed motor cooling are also forecasted. At present, the primary research directions are to reduce the heat generated by the heat source, utilize the latent heat of the coolant, optimize the cooling flow path of the shell, design an axial air-cooling circulation system, and enhance the heat dissipation of the spindle.

“…Zhang et al studied a coupled model of thermal-flow-structure. The simulation results showed that when the diameter of the cooling chan-nel is 7 mm, a spiral cooling system develops a lower temperature but greater radial thermal deformation than a U-shaped cooling system [4]. Su et al established a thermal fluid-solid coupling model of a hydrostatic spindle system using the finite volume method.…”

Based on the finite element simulation software ANSYS Workbench, this study reports the thermal characteristics of a high-speed motorized spindle. The temperature field distribution and axial thermal deformation of the motorized spindle are then detected on an experimental platform. A comparison between the experimental and simulation results revealed the temperature rise of the motorized spindle during the working process. Under steady-state conditions of the working mo-torized spindle, the temperatures of the front bearing, rear bearing and stator were determined as 20°C, approximately 30°C and 25°C, respectively. The axial thermal elongation of the motorized spindle is approximately 10 μm.

“…Gao et al 10 combined heat transfer and nonlinear dynamics, a new theoretical method was proposed to study the thermal behavior of inter-shaft bearing considering the nonlinear dynamic characteristics of double-rotor system. The thermal-flow-structure coupling analysis model was established by Zhang et al 11 to analyze the thermal characteristics of motorized spindle, which provided a good basis for the optimization design of thermal characteristics of motorized spindle. Zhao et al 12 proposed a measurement method of temperature distribution in inner and outer rings of bearing, and a calculation method to study the temperature distribution of bearing and its distribution.…”

As one of the key components of computerized numerical control (CNC) lathes, the dynamic characteristics of spindle-bearing system has a vital influence on machining performance. Analyzing the kinematic error of spindle-bearing system is of great significance for investigating its radial runout and optimizing CNC lathe. The failure mode of CNC lathe spindle-bearing system with thermal effect is defined as the dynamic displacement of shaft end exceeds the allowable radial runout. Firstly, a dynamic model of system with thermal effect under random geometric parameters is presented to carry out the reliability analysis of radial runout. The stochastic perturbation method is applied to determine the first four moments of system dynamic displacement. Random variables and derivatives of system differential equations can be arranged into two-dimensional matrices used with Kronecker algebra. In addition, the reliability and its reliability sensitivity of system are obtained to study the influence of random parameters on the reliability of system. A CJK-6130 CNC lathe is used as a practical example of proposed model. Furthermore, the comparison between numerical calculation and Monte Carlo simulation is used to verify the proposed method. Eventually, the effects of mean values and variances of bearing random parameters on the radial runout are discussed.
